A birds beak helps you identify its habitat by looking at its size and shape. The size and shape will give you an idea of what type of food it eats. A bird will have a beak that is suited for eating food that they find in their habitats such as seeds, nectar, insects, mice or fish. For example, pelicans live close to the ocean. Their beaks are long and they have a pouch in their throat. They catch fish by gulping them out of the water into their throat pouch. If you ever been to Daytona Beach this is a familiar sight. Not something you would see sitting on a park bench in Central Park! Hmmmm <span>sighnoah</span> THANKS!
There is a higher oxygen content in the air of the lungs than that of oxygen-depleted blood and a lower carbon dioxide concentration. This gradient of concentration causes gas exchange during respiration.
